[PATCH RESEND v2 1/1] nfsstat01: Update client RPC calls for kernel 6.9

[Petr Vorel]

[ I'm sorry for the noise if you get this patch 2x ]

6.9 moved client RPC calls to namespace in "Make nfs stats visible in
network NS" patchet.

Changes v1->v2:
* Point out whole patchset, not just single commit
* Add a comment about the patchset

Hi all,

could you please ack this so that we have fixed mainline?

FYI Some parts has been backported, e.g.:
d47151b79e322 ("nfs: expose /proc/net/sunrpc/nfs in net namespaces")
to all stable/LTS: 5.4.276, 5.10.217, 5.15.159, 6.1.91, 6.6.31.

But most of that is not yet (but planned to be backported), e.g.
93483ac5fec62 ("nfsd: expose /proc/net/sunrpc/nfsd in net namespaces")
see Chuck's patchset for 6.6
https://lore.kernel.org/linux-nfs/20240812223604.32592-1-cel@kernel.org/

Once all kernels up to 5.4 fixed we should update the version.

Kind regards,
Petr
